SOLOMON EDWARD AARON, OF BOSTON, MASSACHUSETTS.

BOAT-OPERATING WIN DLASS.

Application filed. September 16, 1921.

T at whom it may concern:

Be it known that I, SOLOMON E. Aaron, a citizen of the United States,residing at Boston, in the county of Suffolk and State of Massachusetts,have invented certain new and useful Improvements in Boat-OperatinglVindlass; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same. i

This invention relates to improvements in windlasses or Windlass enginesfor operating and controlling lifeboats on shipboard.

The object of the present invention is to provide an improved device ofthe character indicated combining simplicity in construction andoperation with both positivencss and safety of control.

The invention consists in the novel construction, arrangement andcombination of parts as hereinafter more particularly described andclaimed.

Two sheets of drawings accompany this specification, as part thereof, inwhich like reference characters indicate like parts throughout.

Fig. 1 is a side elevation of my improved motor driven device;

Fig. 2 is an end elevation of a single unit motor driven device;

Fig. 3 is an end elevation of a double unit motor driven device;

Fig. 1 is a vertical transverse section taken through the drum brakes;

Fig. 5 is a detail view showing the gear shift device.

My present invention lends itself for use both as a single unit adaptedto control the falls ropes from a single lifeboat, or to a double unitadapted to be located amidships to control the falls ropes from twolifeboats, one located on each side of the ship as it may be desired.

Certain essential features of my invention found in common in both thesingle and donble units, will be first described with reference to asingle unit, while certain other features, essential only to the doubleunit, will be subsequently separately described.

In accordance with my invention a suitable base 1 is provided supportingstandards 3 carrying bearings 3 in which is mounted a shaft 2 havingfixed thereon a double falls Windlass drum 4; having a central dividingfin 5 with two brake drums 6 one located at Serial No. 501,062.

each end of the drum. Upon shaft 2 is rotatably mounted a gear 18 havinga clutch hub 19 adapted to be engaged by a sliding clutch 20 operated bya clutch lever 21 which is provided with an operating handle 2e and aspring controlled latch 23 adapted to engage a fixed catch member 23.The ends of shaft 2 are preferably squared as at 25 to receive a crank26 by means of which shaft 2 may be manually rotated as desired torapidly regain the falls ropes.

Mounted in journals 29 carried by frame 3 above gear 18 is a transverseshaft 27 provided with a worm 28 adapted to engage gear 18 to bothoperate and lock the same. The ends of shaft 27 are suitably squared asat 30 to receive an operating crank 31.

Where electric motive power is available a suitable motor 40 may bemounted upon frame 3 having a gear 41 secured on its spindle, and shaft27 is provided with a gear 32 slidable thereon but non-rotatable, exceptin conjunction therewith. being keyed thereto as by key 36. Gear 32 isprovided with a hub 34; having an annular recess 39 adapted to beengaged by fingers 33 carried by a hand wheel 35 having an interiorlythreaded bore adapted to engage threads 37 upon shaft 27. A suitablestop 38 is provided to limit the movement of the hand wheel 35 uponshaft 27.

Under each brake drum 6 is mounted a brake lever 12 pivoted as at 11, atwhich point also is secured a brake band 8 adapted to pass a round thedrum 6 and to be secured as at lO to the lever. Turn buckles 8 areprovided in each brake band to permit ad justments made necessary bychanges in climatic conditions. Brake lever 12 is provided with acounterweight 13 adjustably mounted thereon at the free ends of thebrake lever, of sufficient weight to normally release the tension of thebrake band and is connected to control rope 15 adapted to pass overroller 16 and under roller 17 and thence to the boat.

Where the double unit winch is desired, the shaft 27 is provided withoppositely disposed worms 28, as illustrated in Figs, 3 and 6, by meansof which the falls drums are each rotated in the proper directionrelative to their respective boat falls. Otherwise, each winch unit isconstructed identically the same, each being provided with control 1clutches 20 by means of which either or both of the winch units may bethrown into or out of operative engagementwith gears 18 and hence worms28.

In connection with the construction and arrangement thus described, itwill be noted that the falls to each boat (not shown) when wound upondrums at are controlled both by brakes S and also by the worms 28immeshed in gears 18. Vith clutch 2O thrown into operative engagementwith the hubs 19 of gears 18 the winch is locked irrespective of brakedrums 8, except as it may be operated by the rotation of shaft 27. lVithclutch 2O thrown out of engagement the falls drums will be controlled bybrakes 8 operated from the boat, or upon the release of the brakecontrol ropes 15 will be left free to rotate by reason of the release ofbrakes 8 by means of the counterweights 13 so that the drums 4 may berapidly rotated by hand by means of cranks 26 to recover the falls, orif desired, clutch 20 may be thrown in, where motive power is available,and the falls rapidly recovered through the motor operating through theworm drive.

selectively operating said transverse shaft manually or by power.

2. A device as specified in claim 1 1n which the selective means foroperating the transverse shaft comprises a gear feathered to said shaft,having a hub provided with an annular groove, a member threaded on theshaft and having fingers adapted to engage said groove and a hand gripwhereby the gear may he moved axially of the shaft into and out ofengagement with a power driven gear as desired.

In testimon whereof I affix my signature.
